Bluetooth SIG Announces Deprecation and Withdraw of Legacy Bluetooth Core Spec Version

Samsung BLE SDK (Bluetooth 4.0)

Quoted from: http://developer.samsung.com/ble

Prior to Android, Samsung has released BLE SDK

 Samsung BLE SDK ^beta

Bluetooth low energy (BLE) is a wireless computer network technology which is aimed at novel applications in the healthcare, fitness, security, and home entertainment industries¹⁾. Compared to "Classic" Bluetooth, BLE is intended to provide considerably reduced power consumption and lower cost, whilst maintaining a similar communication range²⁾.

Samsung BLE SDK allows you to develop your own BLE applications which use the Bluetooth Low Energy Client and Server based Protocols. Developers can utilize rich set of API’s provided by our framework to develop Bluetooth 4.0 based applications.

Architecture

The APIs provided by our sdk gives a set of standard GATT procedures and is generic enough to be used with all Bluetooth LE Client and Server based profiles. Below is the basic architecture of our Bluetooth Low Energy stack and framework.

Samsung BLE architecture uses Bluedroid stack which coupled with Samsung framework provides the developer with wide variety of APIs to choose from and provides greater control over Gatt Services, characteristics and descriptors. The framework exposes distinct client and server based classes which can be imported by the application to implement the BLE profiles.

※This SDK is for Samsung Galaxy devices with Android 4.2 and above.

Use Cases

• 
  Heart Rate Profile(HRP)
• 
  Proximity Profile(PXP)
• 
  Alert Notification Profile(ANP)

Profiles are high level definitions that define how services can be used to enable an application or use case. For further information on these profiles, visit : https://www.bluetooth.org/Technical/Specifications/adopted.htm

Proximity Finder (Lost Finder)~BLE (Bluetooth 4.0) Application

I have evaluated several lost finder products.
To my suprised, the new company called as StickNfind is the one which is the most usful one.
https://www.sticknfind.com/

The design normally is set as working in certain distance far.
Excepting StickNFind, other suppliers proximity finder mostly has misworking happened.
For example, when set alarm at 5M, but start woring in 1M or 2M in actual case.
This problem may due to the interference of mobile, WiFi or other wireless device.

Market Products Testing

Therefore, promixity finder actually not only a works for APP (unfortunately most suppliers think so), but BLE design is also a task to enhance the accurancy! Only with the accurancy, this products may able to spread to consumer market widely!

Google Announces Bluetooth® Smart Ready Support for Android Coming Later this Year

Quoted from: http://www.bluetooth.com/Pages/Press-Releases-Detail.aspx?ItemID=167


Today at Google I/O, Google’s annual developer conference, Google announced that in the coming months, Android will include native support for Bluetooth Smart Ready and Bluetooth Smart devices. Phones and tablets with a dual-mode Bluetooth chip running the coming version of Android will qualify as Bluetooth Smart Ready. Bluetooth Smart Ready is the premium designation for devices that are compatible with virtually any Bluetooth enabled product, from keyboards or audio headphones, to the next generation of ultra power-efficient Bluetooth Smart appcessories, like the FitBit Flex or the Pebble watch, coming to market now.

“Working with the big OS providers to offer native support for Bluetooth Smart Ready has been a major initiative within the Bluetooth SIG – we’re thrilled to welcome Android to the family,” said Suke Jawanda, CMO of the Bluetooth SIG. “It’s the hardware and software support that enables Bluetooth Smart Ready devices to seamlessly connect with the billions of Bluetooth devices in use today, and the exploding new market of Bluetooth Smart appcessories. With today’s announcement, Google joins Apple, Microsoft and BlackBerry in providing native software support which is great news for phone and tablet manufacturers, application developers and ultimately, consumers who count on Bluetooth to connect more of their technology.”

 

The native Android support for Bluetooth Smart Ready technology available in the coming months means Bluetooth Smart developers will have an easy way to connect their devices to and distribute their applications within the massive Android ecosystem. Developers will be able to use the new Android API to feed data collected from Bluetooth Smart appcessories, like fitness monitors or medical devices, to their apps running on Bluetooth Smart Ready products, like smart phones or tablets. Once released, any new Bluetooth enabled phone or tablet running Android and featuring a dual mode Bluetooth radio chip will be Smart Ready.

 

ABI projects the market for Bluetooth appcessories (defined as an accessory device with a companion application) to grow from 220 million units in 2013 to nearly one billion in 2016. To support this growth, the Bluetooth SIG has launched a Bluetooth developer enablement initiative which includes a web portal featuring a community forum, training and other resources to make designing with Bluetooth easier and faster. The Bluetooth Quick Start Kit (available now) serves as an introduction to Bluetooth Smart technology. For the Android developer community, the Bluetooth Application Accelerator (coming soon) will provide detailed implementation and developer guidelines to speed time-to-market for appcessory devices.

 

“The real winner here is the consumer,” adds Jawanda. “Bluetooth is truly the people’s technology – it is recognized, trusted, and can already be found in the end user’s pocket. Additionally, it is the only wireless technology to offer the ultra low power consumption and ubiquity needed to bring connectivity to the millions of appcessories coming to market. The Bluetooth Smart products we are going to see in the coming months are going to make life better, give more insight, and enable us all to make more informed decisions.”

Google宣布Android作業系統將於今年支援 Bluetooth® Smart Ready

Quoted from: http://apexscott.blog.ithome.com.tw/post/7661/212237

Google於今日在其一年一度的開發者大會 - I/O大會上，宣布未來幾個月內Android作業系統的版本，將可支援Bluetooth Smart Ready及Bluetooth Smart裝置。未來手機與平板電腦若具備雙模藍牙晶片，並搭載新版Android作業系統，即符合Bluetooth Smart Ready標準。Bluetooth Smart Ready為一進階標準，符合此標準的裝置可與市面上任何藍牙產品相容，包括鍵盤、耳機，以及即將在市場上推出的次世代節能Bluetooth Smart智慧配件(Bluetooth Smart appcessory)等，如FitBit Flex手環、Pebble手錶等。

 

Bluetooth SIG行銷長卓文泰(Suke Jawanda)表示：「與主要大型的作業系統供應商合作，發展支援Bluetooth Smart Ready的裝置一直是Bluetooth SIG致力的目標 。我們對Android作業系統的加入感到非常興奮。透過軟硬體的支援，Bluetooth Smart Ready裝置可與眾多藍牙產品無縫連結。透過今日Google的宣布，Google將加入Apple、微軟及BlackBerry的行列，針對Bluetooth Smart Ready提供原生軟體支援。這項宣布將使手機與平板電腦製造商、應用開發商，以及最終透過藍牙技術連結裝置的消費者受惠。」。

 

Android作業系統在未來的版本將可支援Bluetooth Smart Ready，讓Bluetooth Smart裝置開發商可透過強大的Android 生態系統，簡便的連結及分發其裝置與應用。應用程式開發商可使用新版Android應用程式介面(API)，快速製作使用於智慧型手機、平板電腦等Bluetooth Smart Ready產品的應用程式，輕鬆存取健身記錄器或醫療裝置等Bluetooth Smart智慧配件上的資料。未來任何藍牙手機或平板電腦若搭載新版Android作業系統，並內建雙模藍牙無線晶片，即可為Bluetooth Smart Ready 裝置。

 

市場研究機構ABI預估，從2013年至2016年，藍牙智慧配件（具備應用程式的配件）市場將從2.2億部增至近10億部。為支持未來發展，Bluetooth SIG已推出「藍牙開發者入口網站」（Bluetooth Developer Portal），結合社群、論壇、資源等，讓藍牙相關應用設計更方便、更快速。「藍牙快速入門手冊」（Bluetooth Quick Start Guide）則簡介Bluetooth Smart技術（現已推出）。對於Android開發者社群，「藍牙應用程式開發速成 (Bluetooth Application Accelerator)」（即將推出）將提供詳細的執行與開發原則，縮短智慧配件裝置上市時間。

 

Bluetooth SIG行銷長卓文泰(Suke Jawanda)強調：「消費者將是真正贏家；藍牙技術是全民科技，一直以來備受肯定與信賴，並已普及至眾多用戶；此外，只有藍牙這種耗能極低、無所不在的無線技術能讓市面無數智慧配件彼此連結。未來Bluetooth Smart產品將能讓生活更加美好、並提供更多有用資訊，協助消費者做出最有利的決定」。
